NB - this property charges for electricity use, unlike most airbnb properties in Bangkok. Be aware of that when calculating your budget.
PROS: The road, soi si bamphen is like a village, everybody knows each other, lots of eating options, both European and Thai. I chose to stay at the apartment because I liked that aspect of the road. You get a brief motorbike ride to the metro (MRT) station and further along, the BTS. Plenty of taxis around. Good internet. In terms of location, it's not a trendy area but it has it's charm. You're a 15 minute drive away from Silom area if no traffic, the soi 11 area etc is a long way.
CONS: It could do with a good lick of paint and it's old fashioned but comfortable enough. Presently it's listed as luxury on a budget but it certainly isn't anywhere near luxury and I later realised it's a bit overpriced for Bangkok, especially when you include electricity charges. So if you've got time and not moving into a place on short notice, you might do well to keep your options open. However, the place did serve my basic needs.
The person running the place, Evan, lives on the other side of the alley, directly in front of the apartment and often can be seen with his dogs or friends so is on hand if anything is needed.
